super amoled is nice. but it also burn your screen that is not avoidable. this is the most weak aspect of super amoled panel.

altho i just got my tab 7.7 which uses super amoled as well, i am so worrying about the burn in issues. However, the screen panel is really one of the best which i odn't thik many will dislike
some user has even reported to have their screen burn-in just after 2 weeks.
